23 The equation y = 2x2 - 6x - 80 models the
elevation of a hiking trail in Death Valley. In
this model, x is the distance, in miles, from a
certain starting point, and y is the elevation, in
feet, of the trail compared to sea level.

Which interval for the graphed function contains the local maximum? [–3, –2] [–2, 0] [0, 2] [2, 4]
